Abstract
A method and apparatus are disclosed to provide small cell enhancement in a wireless communication system. The method includes connecting to more than one serving cell. The method further includes triggering a Buffer Status Report (BSR) or a Power Headroom Report (PHR). The method further includes transmitting a Medium Access Control (MAC) control element corresponding to the BSR or the PHR in a serving cell, wherein the serving cell depends on a trigger of the BSR or the PHR.
Claims20
A method of a User Equipment (UE), the method comprising:
- connecting to more than one serving cell;
- triggering a Buffer Status Report (BSR) or a Power Headroom Report (PHR);
- and
- transmitting a Medium Access Control (MAC) control element corresponding to the BSR or the PHR in a serving cell, wherein the serving cell depends on a trigger of the BSR or the PHR.
A method of a User Equipment (UE), the method comprising:
- connecting to more than one serving cell;
- receiving a signaling to configure a mapping corresponding to a data category;
- and
- transmitting or receiving a data of the data category in a serving cell, wherein the serving cell is based on the mapping.
A method of a User Equipment (UE), the method comprising:
- connecting to at least two serving cells, including a first serving cell and a second serving cell;
- establishing at least two logical channels, including a first logical channel and a second logical channel, wherein the first logical channel belongs to a first logical channel group and is mapping to at least the first serving cell but not to the second serving cell, and the second logical channel belongs to a second logical channel group and is mapping to at least the second serving cell, and wherein the first logical channel has higher priority than the second logical channel;
- receiving an uplink grant for a transmission in the second serving cell;
- including a Buffer Status Report (BSR) Medium Access Control (MAC) control element in the transmission, wherein both the first logical channel and the second logical channel have data available for transmission;
- and
- indicating, in the BSR MAC control element, a buffer status corresponding to the second logical channel group when the second logical channel has the highest priority among a set of established logical channels mapping to at least the second serving cell and with data available for transmission, wherein the BSR MAC control element includes buffer status corresponding to only one logical channel group.
