The method comprises assessing a channel to be available for transmission by establishing an on-going transmission to have a received signal strength such as to allow simultaneous transmission in view of a first clear channel assessment threshold; establishing type of transmission of the on-going transmission; and determining, based on the established type of transmission, whether to transmit or to defer transmitting. A corresponding entity, computer programs and computer program products are also provided. ## Claims ### Claim 1 A method, the method comprising: assessing a channel to be available for transmission by establishing an on-going transmission to have a received signal strength such as to allow simultaneous transmission in view of a first clear channel assessment threshold, wherein the first clear channel assessment threshold has a more aggressively set threshold value compared to a static clear channel assessment threshold in view of which the channel might have been assessed to be not available; establishing type of transmission of the on-going transmission, and determining, based on the established type of transmission, whether to transmit data on the channel. ### Claim 2 (depends on 1) The method of claim 1, wherein the determining comprises determining to transmit the data as a result of determining that the type of transmission is not a first type. ### Claim 3 (depends on 2) The method of claim 2, wherein the first type of transmission comprises: a transmission addressed to two or more recipients, a transmission carrying information classified as important, a transmission comprising a request-to-send message, a transmission comprising a clear-to-send message, a multi-user multiple input multiple output (MU-MIMO) transmission, an orthogonal frequency division multiple access (OFDMA) transmission, a beacon frame, a control frame, and/or a trigger frame preceding a first type of transmission. ### Claim 4 (depends on 1) The method of claim 1, wherein the determining is further based on a second clear channel assessment threshold. ### Claim 5 (depends on 4) The method of claim 4, wherein the second clear channel assessment threshold has a value being either more conservatively set threshold value as the static clear channel assessment threshold, or being more aggressively set threshold value allowing a higher number of simultaneous transmissions. ### Claim 6 (depends on 4) The method of claim 4, wherein the establishing comprises establishing that the on-going transmission is of a first type, and wherein the determining comprises determining to transmit simultaneously as a result of determining that the on-going transmission has a received signal strength such as to allow simultaneous transmission in view of the second clear channel assessment threshold. ### Claim 7 (depends on 1) The method of claim 1, wherein the establishing type of transmission comprises: decoding a medium access control (MAC) header and establishing type of transmission based on information in the MAC header, or decoding a physical layer (PHY) header and establishing type of transmission based on information in the PHY header. ### Claim 8 (depends on 1) The method of claim 1, wherein the establishing type of transmission comprises decoding a trigger frame preceding a first type of transmission and establishing type of transmission based on the trigger frame. ### Claim 9 (depends on 1) The method of claim 1, wherein the assessing comprises establishing the first clear channel assessment threshold by a dynamic sensitivity threshold adjustment method. ### Claim 10 (depends on 1) The method of claim 1, wherein the static clear channel assessment threshold is −82 dBm. ### Claim 11 (depends on 1) A non-transitory computer readable stored medium storing a computer program for an entity for handling transmissions, the computer program comprising computer program code, which, when executed on at least one processor on the entity causes the entity to perform the method of claim 1. ### Claim 12 An entity for transmitting in a communications system, the entity being configured to: assess a channel to be available for transmission by establishing an on-going transmission to have a received signal strength such as to allow simultaneous transmission in view of a first clear channel assessment threshold, wherein the first clear channel assessment threshold has a more aggressively set threshold value compared to a static clear channel assessment threshold in view of which the channel might have been assessed to be not available; establish type of transmission of the on-going transmission, and determine, based on the established type of transmission, whether to transmit. ### Claim 13 (depends on 12) The entity of claim 12, configured to determine to transmit the data as a result of determining that the type of transmission is not a first type. ### Claim 14 (depends on 13) The entity of claim 13, wherein the first type of transmission comprises: a transmission addressed to two or more recipients, a transmission carrying information classified as important, a transmission comprising a request-to-send message, a transmission comprising a clear-to-send message, a multi-user multiple input multiple output (MU-MIMO) transmission, an orthogonal frequency division multiple access (OFDMA) transmission, a beacon frame, a control frame, and/or a trigger frame preceding a first type of transmission. ### Claim 15 (depends on 12) The entity of claim 12, configured to determine further based on a second clear channel assessment threshold. ### Claim 16 (depends on 15) The entity of claim 15, wherein the second clear channel assessment threshold has a value being either more conservatively set threshold value as the static clear channel assessment threshold, or being more aggressively set threshold value allowing a higher number of simultaneous transmissions. ### Claim 17 (depends on 15) The entity of claim 15, configured to establish by establishing that the on-going transmission is of a first type, and configured to determine to transmit simultaneously as a result of determining that the on-going transmission has a received signal strength such as to allow simultaneous transmission in view of the second clear channel assessment threshold. ### Claim 18 (depends on 12) The entity of claim 12, configured to establish type of transmission by: decoding a medium access control (MAC) header and configured to establish type of transmission based on information in the MAC header, or decoding a physical layer (PHY) header and establishing type of transmission based on information in the PHY header. ### Claim 19 (depends on 12) The entity of claim 12, configured to establish type of transmission by decoding a trigger frame preceding a first type of transmission and configured to establish type of transmission based on the trigger frame. ### Claim 20 (depends on 12) The entity of claim 12, configured to assess by establishing the first clear channel assessment threshold by a dynamic sensitivity threshold adjustment method. ### Claim 21 (depends on 12) The entity of claim 12, wherein the static clear channel assessment threshold is −82 dBm.
