## Abstract

A method for enhancing uplink and downlink coverage is applied in a base station for the benefit of a terminal user. The base station receives from the user terminal an uplink scheduling request and GPS location. In response, the base station determines a penetration loss level of the GPS location, the penetration loss being attenuation of signals when signals penetrate an outer structure of a building. The base station further determines a transmission frequency of the uplink according to the penetration loss level which is set by reference to base station Tables of penetration loss for buildings and areas within its coverage area, generates a scheduling strategy comprising the transmission frequency of the uplink, and sends the scheduling strategy including the transmission frequency of the uplink to the user terminal for use in intercommunication.

## Claims

### Claim 1

A method of enhancing uplink and downlink coverage between a base station and a user terminal, applicable in a user terminal, the method comprising:
when data to be transmitted is detected, sending an uplink scheduling request and a location of the user terminal to the base station;
receiving a scheduling strategy from the base station, wherein the scheduling strategy comprises a transmission frequency of an uplink; and
transmitting the data to be transmitted to the base station in the transmission frequency of the uplink.

### Claim 2 (depends on 1)

The method as recited in claim 1, further comprising:
receiving a reception frequency of a downlink transmitted by the base station; and
receiving first data transmitted by the base station in the reception frequency of the downlink.

### Claim 3 (depends on 1)

The method as recited in claim 1, wherein the uplink scheduling request comprises Channel State Information (CSI) and a Sounding Reference Signal (SRS).

### Claim 4 (depends on 1)

The method as recited in claim 1, wherein the location of the user terminal is obtained according to a Global Positioning System (GPS) positioning device of the user terminal.

### Claim 5 (depends on 1)

The method as recited in claim 1, further comprising:
Selecting the transmission frequency of the uplink to transmit data according to the location of the user terminal.

### Claim 6

An electronic device comprising:
a processor; and
a non-transitory storage medium coupled to the processor and configured to store a plurality of instructions, which cause the processor to:
send an uplink scheduling request and a location of the electronic device to a base station when data to be transmitted is detected by the electronic device;
receive a scheduling strategy comprising a transmission frequency of an uplink from the base station; and
transmit the data to be transmitted to the base station in the transmission frequency of the uplink.

### Claim 7 (depends on 6)

The electronic device as recited in claim 6, wherein the plurality of instructions is further configured to cause the processor to:
receive a reception frequency of a downlink transmitted by the base station; and
receive first data transmitted by the base station in the reception frequency of the downlink.

### Claim 8 (depends on 6)

The electronic device as recited in claim 6, wherein the uplink scheduling request comprises Channel State Information (CSI) and a Sounding Reference Signal (SRS).

### Claim 9 (depends on 6)

The electronic device as recited in claim 6, wherein the location of the electronic device is obtained according to a Global Positioning System (GPS) positioning device of the electronic device.

### Claim 10 (depends on 6)

The electronic device as recited in claim 6, wherein the plurality of instructions is further configured to cause the processor to:
select the transmission frequency of the uplink to transmit data according to the location of the electronic device.
