Embodiment 1

[0049] According to an embodiment of the present invention, a CB uplink transmission method is provided, Image 6 is the flow chart of the CB uplink transmission method according to the method embodiment 1 of the present invention, such as Image 6 As shown, the method includes the following steps S602 to S604:

[0050] Step S602, the network side notifies the terminal of one or more shared resource identifiers CB-RNTI, and sends the uplink scheduling grant signaling corresponding to the one or more CB-RNTIs to the terminal, wherein the uplink scheduling grant signaling is used to notify the terminal The allocated resources for CB uplink transmission are located between the resources occupied by the uplink control signaling and the resources occupied by frequency hopping, and the CB-RNTI corresponds to the uplink scheduling grant signaling one-to-one.

[0051] Step S604, the terminal performs CB uplink transmission through resources.

[0052] Preferably, in step S602, the ne...

Embodiment 2

[0057] According to an embodiment of the present invention, a CB uplink transmission method is provided, Figure 7 It is a flow chart of the CB uplink transmission method according to Embodiment 2 of the method of the present invention, as shown in Figure 7 As shown, the method includes the following steps S702 to S704:

[0058] Step S702, the network side notifies the terminal of a CB-RNTI and a predetermined rule, and sends an uplink scheduling authorization signaling corresponding to the CB-RNTI to the terminal, wherein the predetermined rule includes that the resource size used by the terminal for CB uplink transmission is N, and the uplink scheduling The signaling is used to notify the resource information allocated to the terminal. The resource information includes the resource location and the allocated resource size. The allocated resource size is M×N, and M is a positive integer.

[0059] Step S704, the terminal performs CB uplink transmission according to predeterm...

Embodiment 3

[0063] According to an embodiment of the present invention, a CB uplink transmission method is provided, Figure 8 It is a flow chart of the CB uplink transmission method according to Embodiment 3 of the method of the present invention, as shown in Figure 8 As shown, the method includes the following steps S802 to S804:

[0064] Step S802, the network side notifies the terminal of a CB-RNTI, the first predetermined rule and the second predetermined rule, and sends high-level signaling to the terminal, wherein the first predetermined rule includes: the size of the resource used by the terminal for CB uplink transmission is N , the second predetermined rule includes: arranging rules for resources allocated by the network side for CB uplink transmission for the terminal, high-level signaling is used to notify resource information allocated for the terminal, the resource information includes the allocated resource size, the allocated resource size It is M×N, and M is a positive ...

Abstract

The invention discloses uplink transmission method and device based on competition. A network side notifies a terminal of one or a plurality of shared resource marks CB-RNTI and sends uplink dispatch authorization signalling (s) which correspond to the one or the plurality of shared resource marks CB-RNTI to the terminal, wherein the uplink dispatch authorization signalling(s) is (are) used for notifying resources allocated by the terminal and used for CB uplink transmission; the resources are positioned between resource employed by the uplink dispatch authorization signallings and resources employed by frequency hopping; and the one or the plurality of shared resource marks CB-RNTI is or are in on-to-one correspondence with the uplink dispatch authorization signalling(s); and the terminal carries out the CB uplink transmission through the resources. The invention reduces the PDCCH overhead and the probability of terminal conflict, mitigates the load of a PDCCH public searching space, also reduces the influence on frequency domain dispatch or PUSCH frequency hopping, and enhances the integral property of the uplink signal sending scheme based on the competition.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a contention based (Contention based, CB for short) uplink transmission method and device. Background technique [0002] In the Long Term Evolution (LTE for short) wireless system, a terminal (User Equipment, UE for short) sends a Scheduling Request (SR) through a Physical Uplink Control Channel (PUCCH) and sends The process of obtaining and sending uplink data is as follows figure 1 As shown: the terminal sends SR; the base station allocates uplink scheduling grant signaling (Uplink Scheduling Grant, abbreviated as UL Grant) to the terminal through the Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH); The configured uplink grant) sends a buffer status report (BSR); the base station allocates an uplink grant for sending uplink data to the terminal through the PDCCH according to the scheduling policy; Send uplink data for PUSC...
